If you need the top level domain (e.g. mysite.com) to also point to StructuredWeb,
you cannot use a CNAME record on the top level domain because of DNS standards limitation,
In that case you need to ask your registrar which hosts your website address to create a URL forwarding
to your top level domain so it redirects to a valid sub-domain which uses the CNAME.
There is no standardized syntax for URL forwarding so you will need to work with your registrar.
